This invention relates to exercising malitude.

ohines of a type wherein a mechanism imparts vibrations to a belt orbody engaging member.

The object of this invention is to'provide an exercising machine of. thevibrator type which will; be efficient in operation, cheap tomanufacture and which embodies a minimum number of operating parts.

The features and advantages of this invention will appear-.from thefollowing description and by the claims appended thereto, referencebeing had to the accompanying drawings in which Fig. 1 is a front viewof the machine with portions cut away and certain operating parts of themachine in section. Fig. 2 is a perspective View of the cabinet used forsupporting andV enclosing the machine. Fig. 8 is a view of the cabinetand the machine '.i elevation showing the belt or body engaging memberin adjusted position and portion of the cabinet top in section. Fig. lis a detail plan view of the top ofthe cabinet showing the swingingboard and the motor locked in the enclosed positions. Fig. 5 is apartial view of the belt showing the means used for hooking the ends ofthe belt on the machine, Fig. 6 is a rear view of one of the balancedcrank arms used in this machine and Fig. 7 is a side view of the machinein elevation.

1n the drawings M indicates an electric motor having an armature shaft11 which has its ends protruding a suitable distance from each end ofthek motor casing 10. On each end of this shaft is mounted a crank armin the form of a balanced ily wheel 12 shown in Figs. 1 and 6.

Each of these wheels is securely held on the motor armature shaft by aset screw such as 13. On each hy wheel 12 there is securely mounted aspindle 14 disposed 180o apart with respect to each other and eachextends from its respective fly wheel in an oblique direction to a pointintersecting a line passing through the longitudinal axis of the shaft11. On each spindle 14 there is loosely mounted a sleeve 15 having anumber of ridges 16 which cooperate to form pairs of eccentric stepsA--A, B-B, and C-C of different am- The outwardly extending end of eachsleeve is provided with a cap 18, which cooperates with the ridge endportion of its respective sleeve 'to form a sphere, the center ofrevolution of which coincides with the longitudinal anis of shaft 11 andfriction washers 19 shown in 1 are each inserted in their respectivecircular groove at the ends of the sleeves adjacent the inclinedsurfaces of fly wheels 12..

The fly wheels 12 are each provided with an aperture 26 adapted forguiding the lubricating oil from its respective sleeve l5 intoaprotective casing or guard 24- and thus preventing any leakage of oilfrom the crank arm and sleeve bearing surfaces.

Oil guards 24- are rigidly secured to motor casing 10 by bolts 35 andeach extends therefrom in a tapered form to a point adjacentthe outerdisposed face of its respective fly wheel 12. These guards are eachprovided with a holer 25 through which trie oil may fall in a. pan 27.This pan is disposed tween the motor and a felt base 28 which serves asa cushion for the motor, the whole being fastened by a numberof bolts 29to a swinging board shown in Figs. 2, 3 and Ll provided for a purposethat will be hereinafter described.

A fabric belt 20, shown in F igs. 3 and 5, has at each end a leathertank 21 sewed thereon and at the end of each tank there is sewed orotherwise secured a reinforcing wire 22 provided for maintaining theaccurate shape of apertures 23 in the tank which permits the easyremoval or hooking the belt in adjusted position on the sleeves 15. asshown in Fig. 3.

.The oil guards 24u being outwardly tapered further serve to prevent thebelt from being accidentally wound around these guards upon its releaseby the operator while the motor isin operation and thus providing aymaximum margin of safety to the user of the machine. f

The swinging board 30 on which the motor is secured is preferablyrectangular' in shape and fits a similar shaped opening in the table topof an ordinary cabinet shown in Figs. 2, 3 and 4. This `board issupported by pivots 36 and 37 wiich extend in bearings in the table top,and a spring pressed plu 33 which apertures 3l and 32 at the ends of theswinging board is provided for holding the motor in the covered oruncovered position, as shown in and 3, respectively. The cabinet may beheld securely in position on the room floor by a belt 38 which has itsends attached to cleats 39 secured to the wooden base molding llt).rl`his belt passes in a cleat 39 secured to the rear wall of the cabinetas shown in Figs. l and 7 and rubber pads which may be secured to thebase molding extend against the l j of the cabinet for damping thevibrations imparted thereto by the motor when in operation.
